axtoolbarbtn

Add buttons to axes toolbar

Description

btn = axtoolbarbtn(tb) adds a push button to the axes toolbar specified by tb and returns the ToolbarPushButton object.

example

btn = axtoolbarbtn(tb,style) adds either a push button or a state button to the toolbar specified by tb and returns the button object. For a push button, set the style to 'push'. For a state button with two states, set the style to 'state'.

btn = axtoolbarbtn(tb,style,Name,Value) specifies button properties using one or more name-value pair arguments.

Add a custom state button for the axes toolbar that turns on and off the axes grid lines.

First, create a program file called mycustomstatebutton.m. Within the program file:

  • Plot random data.

  • Create a toolbar for the axes with options to zoom in, zoom out, and restore the view using the axtoolbar function.

  • Add an empty state button to the toolbar using the axtoolbarbtn function. Return the ToolbarStateButton object.

  • Specify the icon, tool tip, and callback function for the state button by setting the Icon, Tooltip, and ValueChangedFcn properties. This example uses the icon, which you must first save as an image file called mygridicon.png on your path.

When you run the program file, click the icon to turn on and off the grid lines.

function mycustomstatebutton

plot(rand(5))
ax = gca;
tb = axtoolbar(ax,{'zoomin','zoomout','restoreview'});

btn = axtoolbarbtn(tb,'state');
btn.Icon = 'mygridicon.png';
btn.Tooltip = 'Grid Lines';
btn.ValueChangedFcn = @customcallback;

    function customcallback(src,event)
        switch src.Value
            case 'off'
                event.Axes.XGrid = 'off';
                event.Axes.YGrid = 'off';
                event.Axes.ZGrid = 'off';
            case 'on'
                event.Axes.XGrid = 'on';
                event.Axes.YGrid = 'on';
                event.Axes.ZGrid = 'on';
        end
    end

end

Create a custom push button for the axes toolbar that snaps the view of the axes to a 2-D view.

First, create a program file called mycustompushbutton.m. Within the program file:

  • Plot a surface.

  • Create a toolbar for the axes with options to zoom in, zoom out, rotate, and restore the view using the axtoolbar function.

  • Add an empty push button to the toolbar using the axtoolbarbtn function. Return the ToolbarPushButton object.

  • Specify the icon, tool tip, and callback function for the push button by setting the Icon, Tooltip, and ButtonPressedFcn properties, respectively. This example uses the icon, which you must first save as an image file called my2dicon.png on your path.

When you run the program file, click the icon to snap the view of the axes to a 2-D view.

function mycustompushbutton

surf(peaks(25))
ax = gca;
tb = axtoolbar(ax,{'zoomin','zoomout','rotate','restoreview'});

btn = axtoolbarbtn(tb,'push');
btn.Icon = 'my2dicon.png';
btn.Tooltip = 'Snap to 2-D view';
btn.ButtonPushedFcn = @customcallback;

    function customcallback(src,event)
        view(event.Axes,2)
    end

end

Input Arguments

Toolbar, specified as an AxesToolbar object. Create the toolbar using the axtoolbar function, such as tb = axestoolbar.

Button style, specified as one of these options.

StyleDescription
'push'Push button. When clicked once, the button appears to press and release.
'state'State button with two states. When clicked once, the button remains in the pressed or released state until it is clicked again.

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: axtoolbarbtn(tb,'push','Icon','myimage.png','Tooltip','My Icon Tooltip')

Note

The properties listed here are only a subset. Push buttons and state buttons support a different set of properties. For a full list of properties and descriptions for each type, see the associated property page.

Button icon, specified as one of these values. The axes toolbar displays icons as grayscale images. MATLAB® scales down the image to fit, if necessary.

  • File name — Specify the file name as a character vector or a string scalar. The file name can be preceded by a path. The image file must be in JPEG, GIF, or PNG format.

  • Array — Specify an m-by-n-by-3 array of RGB triplets that represent pixels in an image.

  • Matrix — Specify an m-by-n matrix of numeric values that represent pixels in an image.

    • If the values are of an integer type, then specify values between 0 and 63. A value of 0 is opaque and a value of 63 is transparent. NaN is also transparent.

    • If the values are of type double, then specify values between 1 and 64. A value of 1 is opaque and a value of 64 is transparent. NaN is also transparent.

  • Predefined icon — Specify one of the names in this table.

    Icon NameResult
    'brush'

    'datacursor'

    'export'

    'rotate'

    'pan'

    'zoomin'

    'zoomout'

    'restoreview'

    'none'No icon

Example: btn.Icon = 'icon.png'

Example: btn.Icon = 'C:\Documents\icon.png'

Example: btn.Icon = 'rotate'

Button tool tip, specified as a character vector, cell array of character vectors, or a string array. Use this property to display a message when you hover the pointer over the button. To display multiple lines of text, specify a cell array of character vectors or a string array. Each element in the array displays a separate line of text.

Example: btn.Tooltip = 'My Tooltip'
